If you searched for Moisture-proof polar-insulation-case Manufacturer, you probably have a specific use case in mind — not the generic 'protective case'. We have built 150+ custom variations since 2014. Here is what we know.
Below is the catalog data for Moisture-proof polar-insulation-case Manufacturer. Each model has outer dimensions (in mm), inner cavity (mm), empty weight (g), and material specification. Material is engineering PP or PP+GF for impact resistance. Foam set is included: 25mm base + 10mm lid convoluted.
| Model | Outer (mm) | Inner (mm) | Weight (g) | Material | Size Class |
|---|---|---|---|---|---|
| WL1204 | 120×90×40 mm | 115×78×32 mm | 100 g | PP | Phone / Wallet |

The most common model for "Moisture-proof polar-insulation-case Manufacturer" buyers is the WL1204 (120×90×40 mm OD, 100 g empty weight, PP body).
Shell material for Moisture-proof polar-insulation-case Manufacturer is selected per use case: standard PP for general purpose, PP+GF for heavy-duty (10% glass fiber improves impact strength by 35%). Foam is 25 kg/m³ closed-cell PE, 0.5mm CNC cut tolerance. Anti-static ESD foam (10^6-10^11 Ω) available for electronics.
The shell is rated IP68 (submersible 5m / 30 min) ingress protection and validated to MIL-STD-810H Method 516.8 (26 drops at 2.0m). Temperature range is -30 ~ +80 °C. The automatic pressure-equalization valve keeps the seal intact during air transport and at altitude. Latch is a double-throw design rated for 5,000 open/close cycles. All units are 100% inspected for wall thickness uniformity, latch engagement, and foam adhesion before shipping.
We maintain 200+ foam-cut reference designs for Moisture-proof polar-insulation-case Manufacturer, covering camera bodies, drone kits, broadcast gear, military equipment, medical devices, and industrial tools. Send us your equipment list, we will match to the closest reference or draft a new layout free within 24 hours.
Top 5 mistakes we see in 2024: (1) Over-specifying size — buying WL5020 when WL3812 fits. (2) Choosing by price alone. (3) Skipping IP certification. (4) Ignoring latch type. (5) Not requesting lot certificates. All five add up to a 2-3x higher TCO over 5 years.
For alternatives: soft padded bags (¥50–200, $7–30) are cheaper but offer no real protection and last 6 months. Aluminum hard cases ($80–300) are heavier, prone to denting, and 2–4× the price. Carbon fiber cases ($300+) are overkill for 95% of B2B use cases. Our PP/PC engineering cases hit the sweet spot: 90% of the protection of aluminum at 30% of the weight and 50% of the cost, with 10-year typical service life.
Ordering Moisture-proof polar-insulation-case Manufacturer is 5 steps: inquiry (12h response), quote (with recommendation), PO + 30% deposit, production (25 days + QC photos), balance payment + shipment. Repeat orders are 15-20 days. Custom OEM/ODM adds 25-30 days for mold.

Yes. Standard: bulk in master carton (10-50 units per carton). Custom: retail box (printed, $0.80/unit setup), display box, gift box, or flight case for the cases themselves. Setup fee $300-500 per design, 7-day lead time.
Yes. Silver-ion anti-microbial additive in the PP compound, effective against 99.9% of bacteria per ISO 22196. Common in medical cases. Adds $1.50-3 per unit depending on size. Lead time +5 days.
UV-resistant: UV-stabilized PP compound, ASTM G154 500-hour tested, ΔE < 2.0 after exposure. Fire-retardant: UL94 V-0 rated material, no toxic flame retardants. Both add $1-3 per unit, 5-day additional lead time.
Standard: 3.0-3.5mm. Thinnest: 2.0mm (with reduced drop rating). Thickest: 5.0mm (with reinforced ribbing). Wall thickness <2.0mm requires special tooling. We optimize wall thickness per use case during the DFM review.
Standard foam: 3-axis CNC, 0.5mm tolerance, ±0.2mm cut precision. 5-axis foam: 0.3mm tolerance, for complex cavities (lenses, irregular shapes, multiple small items). Adds 3-5 days lead time, $5-15 per foam set premium.
